Description

本発明は、清浄で乾燥した圧縮空気をエアーツールへ供給する供給管路に、冷凍式エアードライヤを介挿する圧縮空気の除湿・乾燥システムにおいて、冷凍式エアードライヤの少なくとも下流側に凝結器とエアードライヤとからなるエアードライヤユニットを介挿し、その凝結器によって圧縮空気を除湿・乾燥して冷凍式エアードライヤを補完し、除湿・乾燥を増進し冷却した圧縮空気をエアーツールへ供給して、エアーツールの機能低下や故障を防止するようにした圧縮空気の除湿・乾燥システムに関する。 The present invention provides a dehumidifying / drying system for compressed air in which a refrigerating air dryer is inserted into a supply pipeline that supplies clean and dry compressed air to an air tool, with a coagulant at least downstream of the refrigerating air dryer. An air dryer unit consisting of an air dryer is inserted, and the compressed air is dehumidified and dried by the coagulant to complement the refrigeration type air dryer, and the dehumidification and drying are promoted and the cooled compressed air is supplied to the air tool. It relates to a dehumidifying / drying system for compressed air that prevents functional deterioration and failure of air tools.

大量の圧縮空気を冷却乾燥可能な冷凍式エアードライヤのなかに、冷凍回路を構成する冷媒圧縮機と凝縮器と膨張弁と冷却器とを備え、該冷却器を配置した冷却室にエアーコンプレッサに連通する圧縮空気導管を配管し、圧縮空気を乾燥かつ冷却して冷凍式エアードライヤへ送り込み、圧縮空気を更に乾燥かつ冷却してエアーツールへ供給するようにしたものがある（例えば、特許文献１参照）。 A refrigerating air dryer capable of cooling and drying a large amount of compressed air is equipped with a refrigerant compressor, a condenser, an expansion valve, and a cooler that constitute a refrigerating circuit, and the air compressor is installed in a cooling chamber in which the cooler is arranged. There is a method in which a communicating compressed air conduit is installed to dry and cool the compressed air and send it to a refrigerating air dryer, and further dry and cool the compressed air to supply it to an air tool (for example, Patent Document 1). reference).

しかし、エアーコンプレッサで生成した高温高圧の圧縮空気を直接、冷凍式エアードライヤへ導入しているため、冷凍式エアードライヤの冷凍負荷が非常に大きくなり、圧縮空気を充分に乾燥し冷却することができず、また冷凍式エアードライヤで乾燥し冷却した圧縮空気を直接、エアーツールへ供給しているため、圧縮空気を充分に乾燥し冷却し得ないままエアーツールへ送り込み、エアーツールが錆たり機能低下し使用不能に陥る問題があった。 However, since the high-temperature and high-pressure compressed air generated by the air compressor is directly introduced into the refrigerating air dryer, the refrigerating load of the refrigerating air dryer becomes extremely large, and the compressed air can be sufficiently dried and cooled. In addition, since the compressed air that has been dried and cooled by the refrigerating air dryer is directly supplied to the air tool, the compressed air is sufficiently dried and sent to the air tool without being able to be cooled, causing the air tool to rust or function. There was a problem that it deteriorated and became unusable.

このような問題を解決するものとして、エアーコンプレッサで生成した高温高圧の圧縮空気を長尺の配管に導入し、自然放熱により略周囲の温度まで降温し、これを小容量のレシーバータンクに導いて更に降温し低露点に調整後、二個のニューエアードライヤに導いて乾燥化させるものがある（例えば、特許文献２参照）。 To solve such problems, high-temperature and high-pressure compressed air generated by an air compressor is introduced into a long pipe, the temperature is lowered to approximately the ambient temperature by natural heat dissipation, and this is guided to a small-capacity receiver tank. After further lowering the temperature and adjusting to a low dew point, there is one that leads to two new air dryers to dry (see, for example, Patent Document 2).

しかし、この従来の装置は、長尺かつ広い導管の配管スペースとレシーバータンク、二個のニューエアードライヤを要して構成が複雑になり、製作費が高価になる問題があった However, this conventional device requires a long and wide conduit piping space, a receiver tank, and two new air dryers, which complicates the configuration and increases the manufacturing cost.

前記問題を解決する他のものとして、エアーコンプレッサで生成した高温高圧の圧縮空気をサイクロン方式の遠心分離器に送り込み、圧縮空気の水分・油分を分離除去して冷凍式エアードライヤへ送り込み、圧縮空気を乾燥かつ冷却後、サイクロン方式の遠心分離器へ導入して圧縮空気の水分・油分を分離除去後、エアフィルタへ送り込んで圧縮空気の水分・油分・スラッジや微生物を除去するものがある（例えば、特許文献３参照）。 As another solution to the above problem, the high temperature and high pressure compressed air generated by the air compressor is sent to a cyclone type centrifuge, the water and oil content of the compressed air is separated and removed, and the compressed air is sent to a refrigerating air dryer. After drying and cooling, it is introduced into a cyclone type centrifuge to separate and remove the moisture and oil of the compressed air, and then sent to the air filter to remove the moisture, oil, sludge and microorganisms of the compressed air (for example). , Patent Document 3).

しかし、前記装置は、エアーコンプレッサと冷凍式エアードライヤの間に高価なサイクロン方式の遠心分離器を配置し、また冷凍式エアードライヤの下流側に高価なサイクロン方式の遠心分離器を配置し、この遠心分離器の下流にエアフィルタの配置を要するため、構成が複雑で製作費が高価になる上に、遠心分離器とエアフィルタの設置に広いスペースの確保を要して、装置が大形化する等の問題があった。 However, in the above-mentioned device, an expensive cyclone type centrifuge is arranged between the air compressor and the refrigerating air dryer, and an expensive cyclone type centrifuge is arranged on the downstream side of the refrigerating air dryer. Since the air filter needs to be placed downstream of the centrifuge, the configuration is complicated and the manufacturing cost is high, and it is necessary to secure a large space for installing the centrifuge and the air filter, which makes the device larger. There was a problem such as

このような点に鑑み、出願人は、エア−タンクとエアーツールとの間の圧縮空気の供給管路に、エアードライヤを収納したドライボックスを配置し、該ドライボックス内のエアードライヤより上流側に気液を分離可能な凝結器を近接配置し、該凝結器は、圧縮空気の導入部に連通する中空筒状の筒状容器と、該筒状容器内の上部に離間して配置した中空筒状の凝結シリンダとを備え、凝結シリンダの上面に圧縮空気を直接衝突可能に設けて、圧縮空気の水分を能率良く多量に除去するようにした、圧縮空気の気液分離システムを開発し、これを既に提案している（例えば、特許文献４参照）。 In view of these points, the applicant arranges a dry box containing an air dryer in the compressed air supply pipeline between the air tank and the air tool, and is located upstream of the air dryer in the dry box. A coagulant capable of separating air and liquid is arranged close to each other, and the coagulant is a hollow tubular tubular container that communicates with the introduction part of compressed air and a hollow that is spaced apart from the upper part of the tubular container. We have developed a gas-liquid separation system for compressed air, which is equipped with a tubular condensing cylinder and is provided so that compressed air can directly collide with the upper surface of the condensing cylinder so that a large amount of water in the compressed air can be efficiently removed. This has already been proposed (see, for example, Patent Document 4).

しかし、前記圧縮空気の気液分離システムは、凝結器によって下流側のエアードライヤの乾燥・冷却機能の負担を軽減し得るが、これをエアードライヤよりも大能力の冷凍式エアードライヤに適用することは事実上難しく、冷凍式エアードライヤに対し圧縮空気の除湿・乾燥および冷却効果に充分な効果を得ることが難しかった。 However, the gas-liquid separation system for compressed air can reduce the burden on the drying / cooling function of the air dryer on the downstream side by the coagulant, but this can be applied to a refrigerating air dryer having a larger capacity than the air dryer. Was practically difficult, and it was difficult to obtain a sufficient effect on the dehumidifying / drying and cooling effects of compressed air for a refrigerating air dryer.

このように構成した圧縮空気の乾燥冷却システムは、エアータンク３から高温高圧（約５０〜８０℃、０.１〜１.５ＭＰａ）の圧縮空気が、空気導管５を介して冷凍式エアードライヤ６に導かれ、その筐体１４内の冷却室１５へ移動して冷却され、圧縮空気中の水蒸気が凝結してドレン２１が生成され、これが冷却室１５の一側の底部に収容されるとともに、除湿された冷却空気が空気導管７に送り出されて、筐体１４の外部のエアードライヤユニット８へ移動する。 In the compressed air drying / cooling system configured in this way, compressed air at high temperature and high pressure (about 50 to 80 ° C., 0.1 to 1.5 MPa) is sent from the air tank 3 through the air conduit 5 to the refrigerating air dryer 6. It is guided to the cooling chamber 15 in the housing 14 and cooled, and the water vapor in the compressed air condenses to generate a drain 21, which is housed in the bottom of the cooling chamber 15 on one side and is housed in the bottom. The dehumidified compressed air is sent out to the air conduit 7 and moves to the air dryer unit 8 outside the housing 14.

前記圧縮空気は、先ずエアードライヤユニット８の上流側の凝結器９へ送り込まれ、そのインレット３３の奥部の通路３８から筒状容器２６内に流入し、該筒状容器２６と凝結シリンダ２８との間の環状の通路４３を下方へ移動する。
この後、筒状容器２６の下方から反転して上動し、凝結シリンダ２８内に導入されて、その上面に勢い良く衝突して水分を凝縮し、凝結した多量のドレンを生成する。
前記ドレンは凝結シリンダ２８および筒状容器１２に沿って流下し、通孔３１から落下してオートドレン２４に滞留し、その溢流がドレンチューブ２４ａに導かれて外部に排出される。 The compressed air is first sent to the condensing device 9 on the upstream side of the air dryer unit 8 and flows into the tubular container 26 from the passage 38 at the back of the inlet 33, and the tubular container 26 and the condensing cylinder 28 The annular passage 43 between them moves downward.
After that, it reverses and moves upward from below the tubular container 26, is introduced into the condensing cylinder 28, and vigorously collides with the upper surface thereof to condense water and generate a large amount of condensed drain.

前記圧縮空気は筒状容器４４の下方から反転して除湿シリンダ４６内に導かれ、その上端部の集気シリンダ６４の凹孔６５へ移動し、該凹孔６５に開口した通孔６６に導かれて連結シリンダ６２内に勢い良く噴出する。
その際、圧縮空気は断熱膨張して冷却され、その水分を凝縮して凝結し、その液滴を集気シリンダ６４および除湿シリンダ４６に沿って落下し、オートドレン２５等に収容される。 The compressed air from which the moisture has been removed by the coagulant 9 is sent out to the intermediate conduit 67, moves to the adjacent downstream air dryer 10, flows into the tubular container 44 from the passage 56 of the inlet 53, and flows into the tubular container 44. The annular passage 61 between the container 44 and the dehumidifying cylinder 46 moves downward.
The compressed air is inverted from below the tubular container 44 and guided into the dehumidifying cylinder 46, moves to the concave hole 65 of the air collecting cylinder 64 at the upper end thereof, and is guided to the through hole 66 opened in the concave hole 65. It is spouted vigorously into the connecting cylinder 62.
At that time, the compressed air is adiabatically expanded and cooled, the moisture is condensed and condensed, and the droplets are dropped along the air collecting cylinder 64 and the dehumidifying cylinder 46 and are accommodated in the auto drain 25 or the like.

また、エアードライヤ１０で除湿ないし乾燥され冷却された圧縮空気は、集気シリンダ６４から連結管５９へ経て出口通路５７へ移動し、アウトレット５２から空気導管７に送り出されて、エアーコンプレッサ収容室１外の空気導管１１へ移動し、その下流側の工場内のエアーツール１２に供給される。
したがって、圧縮空気は水分を除去され、かつ冷却されてエアーツール１２へ供給されるから、エアーツール１２における機能低下や故障の発生を防止し得る。 Further, the compressed air dehumidified or dried and cooled by the air dryer 10 moves from the air collecting cylinder 64 to the connecting pipe 59 to the outlet passage 57, and is sent out from the outlet 52 to the air conduit 7, and is sent to the air compressor accommodating chamber 1. It moves to the outside air conduit 11 and is supplied to the air tool 12 in the factory on the downstream side thereof.
Therefore, since the compressed air is dehydrated and cooled and supplied to the air tool 12, it is possible to prevent functional deterioration and failure of the air tool 12.

更に、本発明はエアーコンプレッサ収容室１内に、エアーコンプレッサ２とエア−タンク３、圧縮空気導管５，７、冷凍式エアードライヤ６、エアードライヤユニット８を収容して、これらを外部環境から保護し、それらの良好な作動を維持し寿命の向上を図れる。
しかも、エアードライヤユニット８の凝結器９とエアードライヤ１０を近接配置して、エアーコンプレッサ収容室１の小形化を図れる。 Further, in the present invention, the air compressor 2, the air-tank 3, the compressed air conduits 5, 7, the refrigerating air dryer 6, and the air dryer unit 8 are housed in the air compressor accommodating chamber 1 to protect them from the external environment. However, it is possible to maintain good operation of them and improve their life.
Moreover, the condensing device 9 of the air dryer unit 8 and the air dryer 10 can be arranged close to each other to reduce the size of the air compressor accommodating chamber 1.

図１１は本発明の応用形態を示し、前述の実施形態の構成と対応する部分に同一の符号を付している。
この応用形態は冷凍式エアードライヤ６の上流側の空気導管５に、エアードライヤユニット８と実質的に同一のエアードライヤユニット６８を介挿し、エアータンク３から吐出された高温高圧の圧縮空気を上流側の凝結器９に導入し、前述のように含有する水蒸気を凝縮し、凝結した水分を除去して除湿するようにしている。 FIG. 11 shows an application embodiment of the present invention, and the same reference numerals are given to the portions corresponding to the configurations of the above-described embodiments.
In this application, an air dryer unit 68, which is substantially the same as the air dryer unit 8, is inserted into the air conduit 5 on the upstream side of the refrigerating air dryer 6, and high-temperature and high-pressure compressed air discharged from the air tank 3 is upstream. It is introduced into the condensing device 9 on the side to condense the water vapor contained as described above, and remove the condensed water to dehumidify.

この後、前記圧縮空気を隣接する下流側のエアードライヤ１０へ導入し、圧縮空気を前述のように除湿シリンダ４６の上面に勢い良く衝突させて水蒸気を凝縮し、凝結した水分を除去して除湿を増進し、これを更に通孔６６に導いて連結シリンダ６２内に勢い良く噴出し、圧縮空気を断熱膨張して冷却し、またその水分を凝縮して凝結し、その水分を除去して除湿ないし乾燥を増進し、この冷却かつ除湿・乾燥した圧縮空気を冷凍式エアードライヤ６へ導入するようにしている。 After that, the compressed air is introduced into the adjacent downstream air dryer 10, and the compressed air is vigorously collided with the upper surface of the dehumidifying cylinder 46 as described above to condense water vapor, remove the condensed moisture, and dehumidify. Is further guided to the through hole 66 and vigorously ejected into the connecting cylinder 62 to insulate and expand the compressed air to cool it, and also condense and condense the moisture to remove the moisture and dehumidify it. Or, the drying is promoted, and the cooled, dehumidified, and dried compressed air is introduced into the refrigerating air dryer 6.

こうして冷却かつ除湿・乾燥した圧縮空気を冷凍式エアードライヤ６へ導入すると、冷凍式エアードライヤ６の冷凍負荷が軽減され、冷凍式エアードライヤ６の稼動や電力消費が低減される。
このようにして冷凍式エアードライヤ６から送り出された圧縮空気は、第１の実施形態に比べて冷却が増進し除湿・乾燥が向上しているから、この圧縮空気が先ずエアードライヤユニット８へ移動すると、その凝結器９によって含有する水蒸気を凝縮し、凝結した水分を除去して除湿する。 When the compressed air cooled, dehumidified and dried in this way is introduced into the refrigerating air dryer 6, the refrigerating load of the refrigerating air dryer 6 is reduced, and the operation and power consumption of the refrigerating air dryer 6 are reduced.
Since the compressed air sent out from the refrigerating air dryer 6 in this way has improved cooling and dehumidification / drying as compared with the first embodiment, the compressed air first moves to the air dryer unit 8. Then, the water vapor contained in the condensing device 9 is condensed, and the condensed water is removed to dehumidify.

次に、前記圧縮空気はエアードライヤ１０によって除湿シリンダ４６内の上面に衝突して水蒸気を凝縮し、この後、通孔６６から噴出し断熱膨張して冷却され、その水分を凝縮して凝結し、冷却と除湿・乾燥が増進する。
したがって、このような圧縮空気が空気導管１１に導かれてエアーツール１２へ供給されると、エアーツール１２の機能低下や故障が強力に低減され、工場の生産性が向上する Next, the compressed air collides with the upper surface of the dehumidifying cylinder 46 by the air dryer 10 to condense water vapor, and then it is ejected from the through hole 66 to be adiabatically expanded and cooled, and the moisture is condensed and condensed. , Cooling and dehumidification / drying are improved.
Therefore, when such compressed air is guided to the air conduit 11 and supplied to the air tool 12, functional deterioration and failure of the air tool 12 are strongly reduced, and the productivity of the factory is improved.
